Specification of Letters Patent.

Patented Sept. 10, 1912.

Application led October 16, 1911. Serial No. 654,945.

To all whom it 'may concern.

Be it known that I, CHARLES K. WOLF, a citizen of the United States, residing near Xenia, in the county of Greene and State of Ohio, have invented certain new and useful Improvements in Harvester Attachments, of which the following is a specification.

My invention relates to improvements in harvesting machines and particularlyr to means for retarding the movement of the grain across the binding table or deck during the initial sheaf forming operation. It is found in practice that in using harvesting machines as ordinarily constructed more or less grain is lost from the binding table, particularly at the initial formation of the sheaf. n

During the operation of the sheaf tying and delivering mechanism the advance of the severed stalks upon the binding table is arrested until the sheaf is delivered from the machine. After the delivery of the sheaf, the wisp of grain collected during the tying and delivering operation is released and advances across the binding table to form the nucleus of the next. succeeding sheaf. The movement of this wisp of grain is arrested by its engagement with the trip lever and binding cord adjacent to the lower edge of the binding deck. The heads of grain being the heavier ortion are inclined to advance more rapi ly down the inclined deck thanthe straw or butt portion of the stalks so that when engaging the trip lever or cord at the lower edge of the deck the stalks are frequently disposed in an inclined or diagonal position. The greater weight of the heads of the grain frequently causes, the initial stalks to tip upon their engagement with the binding cord and trip lever and slide from the binding deck as shown by dotted lines in Fig. 1. This loss of grain -is further augmented by the action of the. vibrator or evener in repeatedly striking the butt of the stalks as they pass down the binding table and particularly after the initial stalks come to rest in a diagonal or inclined position upon their engagement with the trip lever and binding cord whereupon the blow of the vibrator or evener upon the butts of the stalks will fre uently drive the' stalks head first from the inding table as shown by dotted lines in Fig. 1. While but a small wisp of grain is thus lost at each operation, such small losses become quite a considerable amount during a large harvest. To obviate such losses by providing means for retarding the movement of the head portions of the severed stalks enabling the initial stalks to come to rest in an alined positionis one of the primary objects of the present invention.

The object of the invention is to simplify the structure as well as the means and mode of operation of such devices whereby they `rwill not only be cheapened in construction but will be more efficient in use, positive in action and unlikely to get out of re air.

With the above primary and ot er incidental objects in view as will more fully ap-f- `pear 1n tie specification the rinvention consists of the features of construction, the parts and combinations thereof and the mode of operation or their equivalents as hereinafter described and set forth in they claims.

In the drawings Figure 1 is a perspective view of a portion of the binding deck or table of a harvesting machine showing attached thereto the retarding device forming the subject matter hereof. Fig. 2 is a perspective view of a modified form of the retarding device.

Like parts are indicated by similar characters of reference throughout the several views.

- Referring to the drawings, 1 is the binding deck or table arranged at an inclination to the horizontal. y Projecting above the deck or table l adjacent to its lower edge is a trip lever 2 adapted to set in motion the sheaf tying and delivering mechanism upon its operation by the pressure of the sheaf being formed upon the binding deck. Extending through suitable openings in the binding deck adjacent to the trip lever 2 are the packer members 3, which operate alternately to force the severed grain downward tof ward the trip lever and the binding cord 4 which passes adjacent to the trip lever from its supply below the deck to the knotter abotse the deck. (Not shown in the drawing.

Located at the forward side of the deck is the vibrating board 5 which engages the butts of the severed stalks as they pass down the binding table or deck and by repeated blows thereon serves to even the stalks forming the sheaf.

As before stated the heads of the grain being heavier causes the head portions of the stalks to advance faster than the lighter binding cord 4 one or more grain retarding devices 6. Each retarding' device comprises a bar arranged parallel with the path of travel of the grain, having in its upper edge a series of serrations or inclined teeth 7. The teeth 7 are inclined in the direction of engage and positively hold' the stalks, but

said teeth under the influence of the packers 3. rI`hese retarding bars 6, with their inclined teeth, afford suthcient resistance to overcome the rapid advance movement of the head portions of the grain due to their greater weight.

In Fig. l the retarding members have been shown as bars of wood or metal e-X- tending vertically above the plane of the binding deck or table, but it is obvious that the retarding devices may be formed of a flat strip of metal bent and notched as shown in Fig. 2, `to form the retarding teeth. It has been found in practice that the retarding device forming the subject matter hereof effects a great saving in grain, particularly when the stalks are yof short length. For ordinary conditions of use, a single retarding member will be found suflicient, but when the grain is of varying length or the heads of the grain very heavy two or more of the retarding members upon the binding deck or table will be'found desirable. The retarding member forming the subject matter hereof is not dependent for its operation upon the particular mechanism of the harvester, but may be applied to harvesters of any well known construction and may be .applied to machines in use Y as well as to those in process of construe# parent that there is thus produced a device for the purpose mentioned possessing'l the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportion, detailed construction and arrangement of parts, Without departing vfrom the principle involved or sacrificing' any of its advantages.

It is to be understood that the means herein described is but one mode of putting into veffect this invention and the invention is claimed broadly in any of its possible forms tor modifications within the scope of the appended claims. travel of the stalks whereby they will not Having thus described my invention I ,claims will permit the stalks to readily ride over 1.Iny a harvesting machine, a binding itable, sheaf forming and tying devices, a .series of obstructions fixed upon the binding table at the head side only of the sheaf yforming and tying devices adjacent to the point of formation of the sheaf and in the path of travel of the head portions of the stalks whereby such head portions will be retarded while the passage of the butt portions of the stalks will be unretarded, substantially as specified.

2. In a harvesting machine, a binding table, sheaf forming and tying mechanism, a corrugated member carried upon the binding table and in the path of the severed stalks for retarding the movement of the head portions of the initial stalks forming the nucleus of the sheaf in their travel across the bindingl table to the sheaf forme ing devices, while t-he butt portions o-f the stalks are permitted free movement thereon, substantially as specified. f

3. In a harvesting machine, a binding table, a series of inclined teeth fixed on said table and in the path of tra-vel of the head portions of the advancing stalks, which over ride said teeth, substantially as specied.

In testimony whereof, I have hereunto set my handi this 10 day of October 1911.
